More Nokia Windows Phone 7 handset leaked or fan-made video?

The MyNokiaBlog, which has been spreading the rumour of multiple new Windows Phones coming to USA, have published this video which purports to be an internal Microsoft effort showing off new handsets, sent to him from a .ovi email address.

The video appears to be a mis-smash of numerous other videos we have seen before, but with a few bits thrown in showing completely new handsets.
